Esophageal atresia, distal tracheoesophageal fistula, and an air shunt that compromised mechanical ventilation.
Infants with esophageal atresia and a distal tracheoesophageal fistula are predisposed to respiratory failure on the basis of prematurity, respiratory distress syndrome, aspiration of saliva, and reflux of gastric contents into the tracheobronchial tree. Thoracotomy and primary repair may be delayed to allow time for complete evaluation of the infant and respiratory stabilization. Poorly compliant lungs and a large distal fistula can result in selective passage of ventilatory gases into the gastrointestinal tract with resultant hypercarbia. Fogarty balloon occlusion of the distal esophageal segment halts this air shunt and facilitates effective mechanical ventilation.
